of irreversible hydrocolloid impression materials as a function of pouring time: a systematic review.
According to Hill & Jones (1996), ASE% is an indicator of dimensional stability
for the treated samples, which can be used to claim that a dimensional stability
of 20 % and 43 % has been reached for Teak and Melina, respectively, treated for six hours.
The results of the variables dimensional stability
and Vickers microhardness are shown in Tables 3 and 4, respectively.
Amongst the variety of impression materials available, Addition silicone (Vinyl polysiloxane) is very well known for their excellent dimensional stability
and precise detail reproduction.
BASF has added "a new component" to a classic Ultrason E formulation which it says contributes to increased stiffness at elevated temperatures while simultaneously improving the flow characteristics of the PESU melt significantly and without noticeably compromising the dimensional stability
of the material.
Traditional aluminum castings lacked dimensional stability
and increased machining time, which led to higher costs.
The standard Terblend N includes in its attributes a pleasant feel, good acoustic properties and good mould surface replication while the polyamide element contributes dimensional stability
under heat and the good flow properties.
The new ViaMat paper delivers improvements in dimensional stability
and enables higher interconnect densities.
the high costs and lengthy processing requirements of imidized thermosets, and the poor creep resistance and poor dimensional stability
of semicrystalline materials.
The Akroflocks are said to benefit rubber compounders in seals, where flock increases tear strength and improves dimensional stability
and stiffness; rolls, where nylon and cotton flocks impart abrasion and chip resistance; belting, where cotton flock, applied prior to cure, prevents air trapping with minimum effect on adhesion; molded goods, where fiber and wood flours prevent cut growth and increase tear and modulus, and where they also allow air to bleed from the stock, which prevents blisters; and in molded open cell sponge, where wood and cotton flocks prevent cell wall collapse after cure.
GE also says Extem has better creep resistance and dimensional stability
under load at high temperatures than other high-end crystalline thermoplastics like PPS and PEEK.
